ST MKI004V1 User Manual

MEMS 3-axis - ±2g/±6g digital output low voltage linear
accelerometer evaluation board based on LIS3LV02DQ

Features

■ Graphical user interface

■ USB connector

■ Control switches

■ MEMS sensor

■ LED indicators

■ ST7-USB microcontroller

Description

The STEVAL-MKI004V1 is an evaluation kit
designed to provide the user with a complete,
ready-to-use platform for evaluation of the
LIS3LV02DQ, a low power 3-axis linear
accelerometer with digital output. The device
includes a sensing element and an IC interface
capable of translating information from the
sensing element into a measured signal that can
be used for external applications.

Data Brief

STEVAL-MKI004V1

In addition to the MEMS sensor, the evaluation
board utilizes an ST7-USB microcontroller which
functions as a bridge between the sensor and the
PC, on which it is possible to use the graphical
user interface (GUI) included with the kit or
dedicated software routines for customized
applications.
